Jodi Arias claims she had to kill her ex-boyfriend Travis Alexander in self-defense in June of 2008 at his Mesa, Arizona home, even though she had given authorities other stories about the circumstances of his death. She faces the death penalty if convicted of first-degree murder.

On Monday night, HLN’s Dr. Drew played one of the last-known audio recordings of Alexander where he is heard giving an inspirational speech less than a month before Arias killed him.

Alexander’s friend and co-worker Jacob Mefford attended the 2008 speech. He told Dr. Drew, “What I love is when he's speaking from that stage, he's not talking in theory. He's speaking from somebody who has actually come from Hell [and] dealt with it … then turned [his life] around and did something positive with it.”
